I hope that this link works: http://www.amazon.com/exec/obidos/ASIN/0201633612/o/qid=959716532/sr=2-1/103 -0500259-5763053 The book is called: Design Patterns : Elements of Reusable Object-Oriented Software (Addison-Wesley Professional Computing) Amazon price: Our Price: $34.95 Amazon availability: Availability: Usually ships within 24 hours. This book is not that much about OO-software, rather OO-solutions and guidlines on OO-programming. -----Original Message----- From: zope-admin(a)zope.org [mailto:zope-admin@zope.org]On Behalf Of Chris Beaumont Sent: 30 May 2000 08:29 To: zope(a)zope.org Subject: [Zope] What are the best general books on Object Oriented designprinciples?principles? The subject line says it.. What are the best general books on Object Oriented software and database design principles? I'm just starting out, and have no other programming experience to unlearn..(which I have heard is a GoodThing (tm) ) What would you suggest as a good place to start? Obviously one of my goals is that I'd like to be able to start to understand Zope better with this knowledge.... Basically what I want to say is. did any books just seem clearer and less jargon-ridden than the others..? Thanks..

Working with ZopeTime
by Tom Scheidt 30 May '00

30 May '00

Hi All, Im trying to display information based on what day of the week it tis using: <dtml-if "date1 == '<dtml-var ZopeTime fmt=Day>'"> The date1 property on the page I'm calling is "Tuesday". It works when i do this: <dtml-if "date1 == 'Tuesday'"> But not with: <dtml-if "date1 == '<dtml-var ZopeTime fmt=Day>'"> (and yes, the day I'm doing it on is Tuesday). Any ideas? Thanks.

Zope 2.0.1 export
by Paul Gresham 30 May '00

30 May '00

Hi, I have an old linux system running a document store I wrote some time ago in Zope 2.0.1. I've tried exporting my document store but cannot seem to get it re-imported into the latest version of Zope. I can ftp the documents out, but of course lose all the information about each document. Does anyone have any ideas on how to get this working ? Kind Regards Paul Gresham

Re: lambda et al in PythonMethods and DTML
by Tom Neff 30 May '00

30 May '00

I agree with Lalo and others that powerful (but secure) Python features like lambda and map should be available, especially in PythonMethods. You want to encourage people to use these whenever possible instead of hacking the source tree. I also think that it would be a MISTAKE to have a wide divergence between what's available as an expression in DTML versus allowed in a PythonMethod. Otherwise you'll end up spending the rest of the decade answering the same six FAQ's "no, you can't do that in DTML, only in a PythonMethod." The functionality should be the same, and the selling point for the PM is its self contained cleanliness.

hello, i've created some dictionaries in a dtml-document, for example like this: <dtml-call "REQUEST.set('Monday',{'titel' : 'this is to do on monday'})"> <dtml-call "REQUEST.set('Tuesday',{'titel' : 'this is very bizarrr'})"> <dtml-call "REQUEST.set('Wednesday',{'titel' : 'how to do that?'})"> ... and a bit later in the document i need to delete them again ... how can i do that? no one of my DELETE-experiments worked ... thnx.urs

Question about <dtml-in> sorting
by Patrick J.M. Keane 30 May '00

30 May '00

Does sort only sort in one direction? I am looking to sort news items so that the newest items are on top, and when sorting on a date field, I get the opposite behaviour. Any easy way to reverse the sort order? Thanks pk

The unrendered source for a DTML method is reached by appending /document_src to the end of the URL. For example, http://localhost:8080/mystuff becomes http://localhost:8080/mystuff/document_src . In the context of DAVExplorer the solution is to modify the GET so that the /document_src is appended correctly. Not that this can't be done too early since the URL is used for other internal book keeping. I found that the folowing modification works.... In dav_explorer/classes/DAVExplorer/WebDAVManager.java� make the following change at line number 119 ... �� try { �� Response = Con.Generic(MethodName, ResourceName, Body, Headers); �� WebDAVResponseEvent webdavResponse� = GenerateWebDAVResponse(Response,tn); �� fireResponse(webdavResponse); �� } ... becomes ... �� try { �� if (MethodName.equals("GET")) { �� Response = Con.Generic(MethodName, ResourceName + "/document_src", Body, Headers); �� } else { �� Response = Con.Generic(MethodName, ResourceName, Body, Headers); �� } �� WebDAVResponseEvent webdavResponse� = GenerateWebDAVResponse(Response,tn); �� fireResponse(webdavResponse); �� } �� ... note you don't need to change PUT since PUT does the right thing. I've tested this out quickly and it seems to do what I want. The sources to DAVExplorer can be found via a link at www.webdav.org to http://www.ics.uci.edu/~webdav/ enjoy!

IRC clients
by Jimmie Houchin 30 May '00

30 May '00

I haven't been to an IRC chat in over 5 years so this is pretty new to me. I also just built myself a new Linux machine for development and was not familiar with any Linux IRC clients. For those in a similar situation here is a little info on some Linux/*nix IRC clients. I think I'll try X-Chat as I use Gnome. We'll see. See y'all there tomorrow. By the way the links below came from Linuxberg.com aka Tucows. If you click on one it should take you to a page to direct you to the closest mirror. Hope this helps.

Previewing Temporary Images
by Chris Crownhart 30 May '00

30 May '00

I am writing an HTML form that is using the type=file attribute to collect an image from the user. I am also collecting other information and then formatting it on a page in a preview mode. I would like to allow the user to preview their data, with an image, before they elect to save it (in Zope). The problem, I think, is that the IMG tag needs a physical file to point to in order to render the image. Given that the image object is of type FileUpload, once the user presses the submit button, is there a way to display that FileUpload Image without actually saving it in Zope? Thanks for any suggestions, Chris
